Abstract

According to one example of the present disclosure, an access point (AP) comprises a wired interface and a wireless interface. External wireless client devices may associate with the AP and the AP may forward traffic received from the wireless clients. The AP includes a virtual client which is to simulate a wireless client device.

First claim

What is claimed is:

1. An access point (AP) comprising:
a wired interface;
a wireless interface;
a processor and a non-transitory machine readable storage medium storing instructions executable by the processor to:
associate wireless clients with the AP and forward traffic received from the wireless clients;
set up a virtual client in the AP and associate the virtual client with an external AP;
receive, from a server via the wired interface, traffic that is to be sent to the external AP in order to test a wireless local area network (WLAN);
decapsulate the traffic received from the server and forward, by the virtual client, the decapsulated traffic over the wireless interface to the external AP;
receive, from the server via the wired interface, test traffic comprising a first wired protocol frame encapsulated in a tunnel header indicating a virtual client to which the test traffic is addressed;
decapsulate the first wired protocol frame;
convert the first wired protocol frame into a first wireless protocol frame and forward the first wireless protocol frame via the wireless interface over the WLAN to the external AP associated with the virtual client;
receive, via the wireless interface, a second wireless protocol frame from the external AP addressed to virtual client;
convert the second wireless protocol frame to a second wired protocol frame;
encapsulate the second wired protocol frame with a tunnel header and forward the second wired protocol frame via the wired interface over a tunnel to the server
wherein a management IP address of the AP is different from an IP address of the virtual client.

2. The access point of claim 1 wherein the instructions are executable by the processor to set up a plurality of virtual clients in the AP each virtual client associated with a respective tunnel and to receive test traffic from a server via the respective tunnel and forward the test traffic over the WLAN.

3. The access point of claim 1 wherein the instructions to associate the virtual client with an external access point includes instructions to cause the virtual client to scan for an external access point having a specific service set identifier (SSID) and in response to detecting an external access point having said SSID, send an authentication request and an association request to the external access point.

4. The access point of claim 1 wherein the instructions include instructions to cause the processor to set up the virtual client in response to the AP receiving a request from a network administrator to test a WLAN, the request including a SSID of WLAN to be tested and an ID of the server from which the virtual client is to receive test traffic.

5. The access point of claim 4 wherein the instructions to set up the virtual client include instructions to create a tunnel between the server and the virtual client of the AP.

6. A method comprising:
associating, by an access point (AP), wireless clients with the AP and forwarding traffic received from the wireless clients;
setting up, by the AP, a virtual client in the AP and associate the virtual client with an external AP;
receiving, by the AP from a server via the wired interface, traffic that is to be sent to the external AP in order to test a wireless local area network (WLAN);
decapsulating, by the AP, the traffic received from the server and forwarding, by the virtual client, the decapsulated traffic over the wireless interface to the external AP;
receiving, by the AP and from the server via the wired interface, test traffic comprising a first wired protocol frame encapsulated in a tunnel header indicating a virtual client to which the test traffic is addressed;
decapsulating, by the AP, the first wired protocol frame;
converting, by the AP, the first wired protocol frame into a first wireless protocol frame and forward the first wireless protocol frame via the wireless interface over the WLAN to the external AP associated with the virtual client;
receiving, by the AP via the wireless interface, a second wireless protocol frame from the external AP addressed to virtual client;
converting, by the AP, the second wireless protocol frame to a second wired protocol frame;
encapsulating, by the AP, the second wired protocol frame with a tunnel header and forward the second wired protocol frame via the wired interface over a tunnel to the server
wherein a management IP address of the AP is different from an IP address of the virtual client.

7. The method of claim 6 further comprising setting up a plurality of virtual clients in the AP each virtual client associated with a respective tunnel and to receive test traffic from a server via the respective tunnel and forward the test traffic over the WLAN.

8. The method of claim 6 further comprising causing the virtual client to scan for an external access point having a specific service set identifier (SSID) and in response to detecting an external access point having said SSID, send an authentication request and an association request to the external access point.

9. The method of claim 6 further comprising setting up the virtual client in response to the AP receiving a request from a network administrator to test a WLAN, the request including a SSID of WLAN to be tested and an ID of the server from which the virtual client is to receive test traffic.

10. The method of claim 9 wherein setting up the virtual client further comprises creating a tunnel between the server and the virtual client of the AP.
